To all whom it may concerm Be it known that Sncorrno L. CASELLA, a citizen ,of the United States, residing at San Francisco, county of San Francisco, and State of California,-has invented new and useful Improvementsin Basket-Making Machines, of which the following is a specification.

My invention relates to an apparatus which isdesigned for the manufacture of baskets, such as are formed by crossing thin veneers transversely, bending them to form the sides, and then applying a metallic binding strip around the top edges to hold the whole together. I

It consists incombination with mechanism whereby the veneer sheets are assembled, bentinto shape, and the metallic rim applied around the top, and the basket completed.

It also comprises details of, construction which will be more fully explained by reference to the accompanying drawings, in whichv Figure 1 is,a side elevation of my machine. Fig. 2 is a. section of the driving pulley and pawl and ratchet. Fig. 3 isa iron-taview with section of parts. Fig. 4'is a plan view of the folding and crimping-devices. Fig. 5 is a rear view of the frame showing the guides 18 the shaft 25 and the clutch-operating means, the sleeve or collar of the clutch being broken away. I

The apparatus is supported upon a table or bench of any suitable character; such a bench is indicated at C. Upon this bench is fixed the mold or former A, which consists of-a heavy block of metal rectangular in cross section having the part which is uppermost corresponding in size to the bottom of the proposed basket; and the loweimost portion of sufficiently larger areato provide for the divergent or flaring sides of the basket when finished. This-former is suitably supported upon the table C and above it is a depressible plate 2. This plate has a stem 2" extending down into the former A, and surrounded by a spiral spring '3 which normally holds the plate above the surface of the former A, which surface corresponds to the bottom of the proposed basket; i Guides 2 are slidable in'vertical openings in the former to steady the movement of the plate 2.

K In line above the former is a rectangular frame B oi such size and shape that when depressed it will fit over the former A, and will thus act to fold the ends of veneers which have been previously placed upon the plate 2, and cause thefolded-sides of the venee to substantially fit the sides of the former.

Beneath the hollow rectangular frame B is a plate 5 having a central stem 6 extending upwardly into a guide as at 6". The stem is slotted longitudinally, and

- and bent around the bottom of the former. insertion of the edges oi the basket intothe binding a pin 6 in the slot serves to limit the movement of the stem and plate. Above the stem is a spiral spring 7 I which presses upon the-stem 6 and thus normally holds fixed guides or stops 10 locatedone behind and the other at one side of the plate with relation to the seat of the operator so that they may be rapidly and correctly placed. By pressure upon a foot lever mechanism is thrown into gear as will be hereafter described which will depress the hollow frame B and the plate 5. The plate 5 first rests upon the veneers lying on the plate 2, thus temporarily locking them in position. The continued movement of the parts forces the plate 5 upwardly against the tension of the spring 7, and

the continuation of the movement carries the hollow' frame B which is carried by any suitable yokes or connections B downwardly over the plate 2 and former A, and the projecting ends of the veneers are .thus folded down over the former. The movement still continuing then' depresses the plate 2, and the lower edges of the veneers are caused to slide down the former sides until they enter the groovesioi the V-shaped metal binding strips which have been previously placed After the strips, the latter are compressed or crimp'ed upon the edges oi the veneers, and the basket is thus finished ready for, removal from the former.

The metal binding strips'are usually made oi sheet Q tin cut into narrow strips and folded into V-form.

These'strips 17 are placed, in holders which consist of vertical guides 18 so disposed that a pile of the V-shaped'stripsmay be placedin each one with the open sides upward. --As these strips rest in the holders,

one upon each side of the apparatus, they do not fit I, snugly, but there is a little space between the inside bottom of each V-shaped strip and the outside bottom of the next strip above, so that by means of a'suitable apparatus, the strips may be forced forward from the carriers'intoposition uponeach side of the former A and'in readiness to be folded so'that the ends-of, the

folded strips will overlap upon the iront'and back of the former, and .thus form a complete binding when crimped :upon the basket edges. The guides 18 in 'which the binding strips are placed are located behind the position of the former, and beneath the linesoi the strips are channeled slides 18*,each having a small advancedthese pins contact with the lower V-shaped edges of the two bottom strips, and thus carry them forward opposite the former as before described. When the slide is retracted these strips are left in position with the central part of the strips corresponding with the sides of the former, and the ends which project forward and back are just long enough to overlap when folded upon the front and back of the former.

. The folding device consists of rectangular yokes 11 slidable in guides transversely with relation to.the table and former, and'the ends of these yokes striking the projecting ends of the previously placed binding strips, will'fold them simultaneously about the back and front of .theformer and overlapping sufficiently to be subsequently crimped and interlocked.

In order to properly overlap the V-shaped binding strips, one of the 'yokes' 1] has the lower edge inclined or beveled as shown at 12, so thatas it folds the strip upon that side, the tendency isto lift the inner ends of-the strip by reason of this beveled construction of the yoke. The yoke upon the opposite side has its bevel 12 inclined in the opposite direction from the bevel 12, that is the ends of the yoke which contact with the binding strip are under-cut, and when pressure is applied the tendency will be to keep the ends of this strip down upon the surface while theother one being correspondingly raised above the surface and above the strip which is held down, will thus overlap this lower strip, and when the edges of the basket are forced down after being folded over the former A, as previously.

described, they will enter the open grooves of the strips, and will press the end of the upper strip .into the end of the lowerstrip so that the binding strips will then be substantially in line allthe way around the basket and ready to be crimped thereon.

The crimping is effected as follows: 14 are separable plates having the edges 14 corresponding with the four sides of the former A and lying just beneath it. The binding strips inclose these edges and the edges of the basket when forced into the binding strips are aslo in line with these outwardly moving plates 14. 13 is a wedge-shaped block carried by a stem 15 and actuated by a cam 16 so that when this block 13 is forced up-- wardly, its four sides contacting with the outwardly movable parts 14. it will be seen that these parts will be simultaneously forced outward, and their edges 14 will act to compress and crimp the binding strips upon the edges of the basket fabric, because the outer sides of the binding strips are held between the arms of the yokes 11. and against the interior of these yokes which thus form the rigid support against which the metal is crimped. The inner surfaces of these yokes may be corrugated or otherwise formed with .indentatibns or irregularities which will indent the binding strips into-- the material of the basket so as to prevent the accidental separation after the basket is completed.

The mechanism may be driven in any suitable manner. 'I have heres hown' power applied to a belt pulley upon a-shaft 25, and from this shaft power is transmitted by a belt 26 to a pulley 27 loosely mounted upon a shaft 28 through which power is transmitted to the various cams by which the parts heretofore described are actuated. 1

Any suitable form of clutch mechanism may be employed to temporarily lock the loose pulley 27 to the shaft 28 so as to transmit motion to said shaft and the parts, actuated thereby I have here shown one form in which thehub of the ratchet teeth 19.

9 is a pawl extending parallel with the shaft and adapted to be moved into and out of engagement with the'te'eth 19. This pawl is carried upon a pin 9 which is at right angles with the pawl, and fits into a radial opening in the shaft 28, and is normally pressed out- .ward by a spiral spring 9*. When the pin 9 is depressed, the pawl 9 is moved down so as to substantially coincide with the periphery of the shaft 28, and will be out of contact with the ratchet teeth 19 of the pulley. The pulley will thus turn freely upon the shaft when motion is transmitted to it through the belt 26 as previously'described. This pawl 9 is normally held in its depressed position by an arm 30 which is actuated by a foot lever 31 and a connecting arm or link 32 so that when the operator depresses the foot lever; the action of the connected parts will release the pawl 9 and allow it to be forced outward by the spring 9 and into engagement with the teeth 19 of the ratchet within the hub of the wheel 27 and the motion of the wheel will thus be transmitted to rotate the shaft 28.

The metal binding strips having been placed with relation to the former as previously described and by a separate treadle and foot mechanism to be hereafter described, therotation of the shaft 28 will act through came 8 and cam-actuated levers 33 to advance the yokes 11, and foldthe binding strips about the former as heretofore described. A further revolution of the shaft causes the cam 34 to act through a connecting rod 35 upon a fulcrumed tilting lever 36 which is con nected with the slide 37, which slide carries the hollow frame B, and the connected parts by which the veneers are folded. The release of the foot lever 31 immediately after the'pawl Qhas beenengaged with the ratchet, allows it to remain in engagement until a single revolution of the shaft has been effected when the pulley 27 has the internal arm 30 will act to again depress the pawl and disengage it from the pulley and the shaft and cams come thereby to a stand still.

The mechanism for advancing the strips of metal 17 as previously described consists of a suitably constructed clutch 20 mounted upon the shaft 25, and upon this shaft is fixed a cam 38 which by connecting rod 39. and .fulcrumed lever 40 acts upon the slide 18" by which the strips are periodically advanced.

As shown in the rear end view, Fig. 5, the arm 38 iscarried by the clutch drum 20, and is strictly a crank-armdnstead of a cam, although either would serve to reciprocate the lever 40 and the pusher slides 18". The drum 20 with its internal teeth is normally stationary and the shaft 25 carrying the pawl revolves within it. A sleeve or collar 20 is slidable upon a key or feather on the shaft 25 and when moved toward the clutch case 30 it may throw the pawl outward to engage the internal ratchet teeth of the part 20 thus causing it to revolve in unison withthe shaft, and

force the clamping strips forward. This operation is effected by connecting the foot lever 31" with the clutch actuating sleeve 20 by any suitable connection which will disengage this sleeve when the foot lever is depressed. In the present case connection rod a-b and a bell crank lever 42 will effect this result.
